Season-by-Season Breakdown

Peak Season — Cherry blossom season (April) and autumn foliage (October)

Peak season in Seoul coincides with the most favorable weather and the highest visitor numbers. Expect clear skies and comfortable temperatures, but also premium hotel rates and crowded attractions like Gyeongbokgung Palace and N Seoul Tower. Booking at least 2–3 months ahead is strongly recommended.

Pros: Best weather, all attractions operating at full capacity, vibrant atmosphere.

Cons: Higher prices (daily budgets start around $120), longer queues, accommodation books out fast.

Shoulder Season

The weeks just before and after peak season deliver an excellent balance. You will still enjoy pleasant weather while benefiting from thinner crowds and lower prices. This is often the sweet spot for budget-conscious travelers who do not want to sacrifice comfort.

Pros: Fewer tourists, moderate prices, pleasant conditions.

Cons: Some seasonal activities or tours may have limited schedules.

Off-Season

Visiting Seoul during the off-season is not for everyone, but it rewards the adventurous. Accommodation rates can drop significantly — budget travelers can get by on as little as $40 per day. You will have popular spots like Changdeokgung Secret Garden practically to yourself.

Pros: Lowest prices, authentic local atmosphere, no queues.

Cons: Some businesses may close, weather can be unpredictable.
